If the minimum (threshold) energy for the emission of an electron from the surface of a particular metal is 2.51 X 10-19 J, what is the kinetic energy of an electron emitted from the surface of the metal when it is irradiated by electromagnetic radiation of wavelength 175 nanometers?
Planck's constant = 6.626 x 10-34 Js
Speed of electromagnetic radiation = 3.0 x 108 ms-1
